OPERATING INSTRUCTIONS
Exterior Lights Self Test
This feature allows the operator to verify and inspect exterior lighting
operation typically performed during a pre-trip inspection. When the feature
is engaged, via a switch on the key fob, it will illuminate the:
• park lights
• side marker lights
• hazard/turn signals
• low & high beam headlights
•
first set of fog lights
• stop/brake lights
After turning these lights off, the system will resume testing the first set
of lights. The light test will eventually stop on its own. The operator may
interrupt the test by turning the vehicle off or pressing the switch a second
time while the test is running. The operator can verify the functionality of
the lights by visibly watching the lights from outside the vehicle during the
test or can read the instrument cluster for any faults displayed that are
lighting related.
To start the Exterior Light Self Test feature:
1. Park the vehicle and set the parking brakes.
2. Insert the key into the ignition, start the engine and allow the
vehicle to run through its Power On Self Test.
3. Press the momentary switch on the key fob to start the cycle.
